Limited-run McLaren 12C and 12C Spider models will be built to celebrate the sports car maker's 50th anniversary.

The McLaren 50 12C and 50 12C Spider feature a range of styling and specification upgrades. On the outside, both models get a redesigned front bumper with an extra lip that increases downforce, and a black Formula One-inspired McLaren badge.

There are also bespoke alloy wheels finished in Satin Black – these are 19in diameter at the front and 20in diameter at the rear. Three exterior colours are available – Carbon Black, Supernova Silver or McLaren Orange.

Inside, the 50 12C models get a full leather upgrade and a special plate on the driver's door. Mechanical changes are limited to the addition of carbon ceramic brakes.
